Answer:
a. $15 + 8p
b. $175
c. $975
d. $495
Step-by-step explanation:
*Im using $ instead of euros
The equation is $15 + 8p
b. you plug in 20 which would be 15 + 8(20), the answer for this would be 175
c. For this you would do the same thing 15 + 8(120), the answer would be 975
d. Since this is saying per week and there are 4 you would multiply 15 by 4 first and get 60 then you plug it in, 15 + 8(60) = 495

Answer:
D. 22/1=x/3
Step-by-step explanation:
Well what you multiply by the top you must do the bottom and opposite way also goes, sometimes so to get three as shown in (x/3) you must use the 1 from (22/1) times something to equal 3. In this it would be 1*3=3 so I multiplied three to the bottom and what I do the the bottom I haft to do to the top so 22*3=x and x is equal to 66 witch makes (D. 22/1=x/3) the correct option. If you want or need to check a good way to is to use a calculator to multiply 22*3 just as a small check up.

Determine the value of k that would make these two functions inverses.
Answers
Answer: K = 6
Step-by-step explanation:
If you find the inverse of the inverse function, it will return back to initial function.
The inverse of r^-1 (x) will give r(x).
To find the inverse of r^-1(x), let it be equal to y. Interchange y and x for each other and make y the subject of formula. That is,
Y = 2x^2 - 14
Interchange y for x
X = 2y^2 - 14
2y^2 = x + 14
Y^2 = x/2 + 14/2
Square both side
Y = sqrt ( x/2 + 7 )
It is only when K = 6, that will can get the value above.

Answers
Answer:
Please mark be brainliest and I hoped this helped!
x = 80°
Step-by-step explanation:
These are both isosceles triangles, so the top 2 angles are both 65°. The last angle of that triangle is 180° - (65° + 65°) which is 50°. Then, the opposite of that angle is in the next traingle. It is also 50°. So the 2 base angles are both 50°, so x is 180° - (50° + 50°) which is 80°.
The measure of angle 'x' is 65 degrees and this can be determined by using the properties of the isosceles triangle.
Given :
Angles --- [tex]65^\circ[/tex] and x
The following steps can be used in order to determine the measure of angle 'x':
Step 1 - Both the triangles are isosceles triangles because in both the triangles two sides are similar.
Step 2 - Let the upper triangle be ABC and the lower triangle be DBE.
Step 3 - The angle B of the triangles can be calculated as:
[tex]\angle A + \angle B + \angle C = 180[/tex]
[tex]65+65+\angle B = 180[/tex]
[tex]\angle B = 50^\circ[/tex]
Step 4 - Now, angle 'x' can be calculated as:
[tex]\begin{aligned}\\\angle D + \angle B + \angle E &= 180\\x+x + 50 &= 180\\2x &= 130\\x &= 65^\circ\\\end{aligned}[/tex]
The measure of angle 'x' is 65 degrees. Therefore, the correct option is B).

James earns $1000 weekly base pay as a sales-person and gets a 10% commission on everything he sells. It is said that he sold $20,000 worth of merchandise last month, how much did he earn for the month? Provide an explanation :)) A. $4,000 B. $22,000 C. $6,000 D. $2,000
Answers
Answer:
Option C.
Step-by-step explanation:
It is given that James earns $1000 weekly base pay as a sales-person.
We know that, we have 4 weeks in a month. So, monthly salary of james is
Monthly income [tex]=\$1000\times 4=\$4,000[/tex]
It is said that he sold $20,000 worth of merchandise last month and he gets a 10% commission on everything he sells.
Commission [tex]=\$20,000\times \dfrac{10}{100}=\$2,000[/tex]
Total amount = Monthly income + Commission
[tex]=\$4,000+\$2,000[/tex]
[tex]=\$6,000[/tex]

Answer: If you want to make more cookies then what is called for in this situation then you would need 6 cups of milk.
Step-by-step explanation: You have 2 cups of milk and 3 cups of flour of course. In order to make a complete batch you need 2 cups of milk and 3 cups of flour. In order to make a second batch you need the same things as you did for the first batch. Therefore two batches of cookies requires 4 cups of milk and 6 cups of flour. In this situation you want to make 3 batches of cookies. The required items are 6 cups of milk and 9 cups of flour.
The sweater Ingrid wants to buy is $30.
It is on sale for 33% off. If the sales tax is
7%, what is the total cost of the sweater?
Round to the nearest cent, if necessary.
Answers
Answer:
Sweater will be $21.51
Step-by-step explanation:
cost of sweater $30.00
Sale of 33% off comes to $9.90/off ($30 × 33% = $9.90)
$30.00 - $9.90 =$20.10
Sale cost of sweater is $20.10
$20.10 × 7% sales tax = $1.41
$20.10 + $1.41 = $21.51

Sarah is playing a board game. The probability that Sarah will score a point on her next turn is 1/3. Which statement describes the probability that Sarah will score a point on her next turn?
Answers
Complete question:
Sarah is playing a board game. The probability that Sarah will score a point on her next turn is 1/3. Which statement describes the probability that Sarah will score a point on her next turn?
A. likely
B. certain
C.unlikely
D.impossible
Answer:
C. unlikely
Step-by-step explanation:
If the probability that Sarah will score a point on her next turn is 1 which is 100%, then it will be certain that she will score a point on her next turn.
Again, If the probability that Sarah will score a point on her next turn is ¹/₂ which is 50%, then it will be likely that she will score a point on her next turn.
Also, If the probability that Sarah will score a point on her next turn is ¹/₃ which is 33%, then it will be unlikely that she will score a point on her next turn.
Furthermore, If the probability that Sarah will score a point on her next turn is 0 which is 0%, then it will be impossible that she will score a point on her next turn.
Thus, the correct statement for the given question is "unlikely"
